Programming Ruby 3.2 (5th Edition): B4.0 page 507, require bigdecimal

@noelrappin

page 507, in BigDecimal, fourth paragraph from bottom, first line :

To use BigDecimal, you must require bigdecimal in your application. Once you’ve required
                            -----> ^          ^

Should be : require “bigdecimal”, like you need to require “date” on page 501.

First Post!
